Power range: 200kW – 1200kW (@400V), AC Voltage range: 200V to 400V. Maximum efficiency: 98.5%. DC Voltage range: 1,51xVac – 885V. Protection degree: IP20.

With an output voltage up to 3300V DC and DC output current up to 6000A, FRIEM rectifiers have the highest levels of performances, reliability and customization thanks to a robust structure, N-1 semiconductors redundancy, control system self-diagnostic and long operation life achieved with low operation temperature.

The ED-Con is integrated in the traction systems to dissipate the energy during the vehicle braking. Together with the associated resistor banks in traction substations, instead of on-board resistors, it reduces the vehicle weight, the energy consumption and solves the problem of heat in the tunnels.
